'''Gimilzagar''' was a [[Númenórean]] of the royal house, the younger son of King [[Tar-Calmacil]] the eighteenth ruler of the island kingdom. His line of descent made him the great-uncle of Tar-Calmacil's grandson [[Ar-Adûnakhôr]], who broke with tradition by taking his royal name in the [[Adûnaic]] tongue. Some sources suggest that Gimilzagar was the ancestor of [[Inzilbêth]] the mother of [[Tar-Palantir]], though the details of this ancestry are open to question.
